Patented Aug. 22 1922,

To all whom it may concern Be it known that T, ALBERT ABBE GRIS- WOLD, a citizen of the United States residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Flexible Shingles, of which the following is a specification.

My invention has reference to an improvement in shingles and more particularly to an improvement in the flexible shinle shown and claimed in my United States Fatent No. 1,274,410, August 6, 1918.

In the construction of roofs and the like on which flexible shingles are used, it is necessary to hold down the free or lower end of theshingles so as to prevent bending or curling up of the shingles and allowing rain, snow or sleet to beat up under the shingles, thereby giving an unsightly appearance and causing the roof to leak.

The object of my invention is to improve the construction of such a flexible shingle, whereby the outer or otherwise free end of the shingle is provided withimproved and simplified means for securing the same in place on aroof or the like and thecost of construction materially reduced.

A further object of my invention is to improve the method of laying such flexible shingles, whereby the contraction and expanslon actions of the roof boards, on the shingles, are compensated for, by the method of laying the shingles.

My invention consists in the peculiar and novel construction of a flexible shingle, said flexible shingle being provided with means for holding down the outer or What has heretofore been the free end of the shingle and method of laying such shingles, whereby the roof boards may contract or expand without afl'ecting the shingles.

Figure 1 is a plan view of a portion of a flexible shingled roof, said flexible shingles being rovided with my improved means for se iring the outer or free ends of the shing es in places on the roof and showing the space between the edges of the underturned flap and the edges of adjacent shingles, to allow for contraction and expansion of the roof boards.

Fi re 2 is a plan view of my improved flexib e shingle.

Figure 3 is an inverted plan view of my improved flexible shingle.

sectional view taken on line 5, 5 of Figure 3, through the shingle.

in the drawing 6 indicates the sheathing or a roof and 7, 7 my improved flexible shingles. The roof sheathing 6 may also represent the sheathing on the outer walls of a building. The flexible shingles 7, 7 may be constructed of paper, felt, asphalt and ground slate or other flexible compositions or fibrous material. Each shingle 7 has its outer end or corner bent underneath and formed into a flap 8 and a flat fasten- 1ng member 9 extends transversely across the end of the shingle between the body of the shingle and the flap 8. The flat fastening member-9 has a flat central portion 10, bent out portions 11, 11 and flat end portions 12, 12 which lie parallel with the body of the shingle and are spaced from the body of the shingle approximately the thickness of a shingle, as shown in Figure 5.

The fastening member 9 is formed preferably of sheet metal and it may be held in place by the flap 8, it may be secured in place by cementing the flap to the body of the shingle at each side of the fastening member or it may be secured in any other well known way, the object being to hold the fastening member in place without penetrating through the flap, as in my previous patent cited.

In shingling a roof or the like with my improved flexible shingles 7, 7 the shingles are laid diagonally. Each course is laid by placing a shingle 7 of the next up per course over a shingle 7 of the next lower course in a position for the ends 12, 12 of the fastening member 9 to go under the edges of two adjacent lower shin les. The shingle is then moved upwards an the ends 12, 12 of the fastening member 9 forced under the adjacent edges of two shingles in the lower course, as shown in Figure 1, thereby securing the lower end of the shin- 'gle to two shingles previously nailed to the roof, in the lower course. I

In moving the shingle upwards a slight space 13 is left between the edges of the flap 8 and the adjacent edges of the two Mill the means for holding the fastening member in place between the flap and the body of the shingle, as any construction or material could be used for the fastening member and the fastening member could be held in place or secured by any well known means.

Having thus described my invention I 20 claim as new 1. A flexible shingle having a bent under flap and a transverse fastening member secured wholly between the flap and the body of the shingle, for the purpose as described, the bent under flap holding the fastening member in place, between the flap and the body of the shingle.

2. A flexible shingle having a bent under flap and a transverse fastening member secured wholly between the flap and the body of the shingle and means for securing the fastening member in place, consisting of cementing the flap to the shingle, at each side of the fastening member.

In testimony whereof, I have signed my name to this specification.

ALBERT ABBE GB-ISWOLD.
